A few years ago, I had posted a video showing a cool trick that can be used to hypnotize a chicken. In today's post, we will dig a bit more into this whole chicken hypnosis thing.
The trick is quite simple. All you have to do is hold the chicken's head down against the ground, and draw a straight line using a stick, your finger, a piece of chalk or whatever.
The line should start at the beak and extend straight outwards, in front of the chicken. If done properly, the chicken -or rooster- will be put into a state of trance and lie still for anywhere from 30 seconds to 30 minutes! To de-hypnotize the chicken, just clap your hands or give it a gentle push. It may take a few tries to awaken the bird. Here is a video demonstrating the process:
In chickens, this is most probably a vestigial trait as it doesn't seem to have a useful purpose. The chicken doesn't make a good job hiding the fact it's still alive. Its obvious that is breathing and we can see some eye movement and blinking.
Who discovered the trick?
I guess we will never know the answer to this. Probably a farmer with lots and lots of free time!
Most farmers are familiar with the trick as the method is passed down from generation to generation. The first known written reference comes from the 1646, in "Mirabile Experimentum de Imaginatione Gallinae" by Athanasius Kircher, a 17th-century German Jesuit scholar and polymath who published around 40 major works.
Using a straight line is not the only way to hypnotize a chicken. Here's a video demonstrating 2 more methods to get the same effect:
And here is another video, this time using a perpendicular to the bird line:
Why hypnotize a chicken, some may ask. It's harmless and fun, so I guess it's ok when done in moderation :)
